Description

The method of editing graph on touch screen

Technical field

The present invention relates to the application of touch-screen, refer in particular to method at editing graph on touch screen.

Background technology

Continuous development along with electronic technology, touch-screen more and more is subjected to pursuing of people, because touch-control input device possesses the facility of hommization, reach the advantage that does not account for any space, the user can easily realize the various functions of mouse by finger, so nowadays, not only mobile computer has all added the design of Trackpad, and the notebook computer of full touch-control appearred supporting, use more widely as PDA(Personal Digital Assistant), flat computer (table PC) etc., serve as main input with screen especially with contact panel, the mode of output message is so electronic product is also listed touch-control input device in the main mode of its man-machine interface gradually.

Make a general survey of existing touch-control electronic product, the user is when using its editing graph, thereby all be only to utilize finger to select corresponding button option to select corresponding order, to open the picture that carries annex in the computing machine is example, when the user finishes a figure as a curve after, if need the black of acquiescence is changed to other color, must must click the replacing of choosing corresponding color icon can finish color, go out more color though the user is also can be on the basis of a color self-defined, if but the user is when drawing, just must finish according to above-mentioned set mode, like this such as when describing the figure of a riot of color, operating must be more loaded down with trivial details, need choose different chromaticity diagrams to be marked with the needs that satisfy different color again and again.

Therefore need for users provide a kind of easier can be in the method for editing graph on touch screen.

Summary of the invention

The actual technical matters to be solved of the present invention is how a kind of method that can be controlled at editing graph on touch screen by pressure is provided.

In order to realize above-mentioned purpose of the present invention, the invention provides a kind of method of editing graph, it may further comprise the steps: the project of determining the editing graph of wanting; Utilize an object on the described editor's of needs figure, constantly to exert pressure; The described project that needs graphics edition changes according to the continuous variation of this pressure.

The method of utilizing pressure to come editing graph of the present invention has not only replaced traditional needs and has edited the complicated way that could realize purpose repeatedly, and utilized pressure to realize editing graph, and gesture operation is very simple, and effect is obvious, controls the editor of figure easily.

Description of drawings

Fig. 1 is that the present invention is a synoptic diagram of example with a drawing tools;

Fig. 2 A-2C is the change procedure figure that for example understands an embodiment according to the present invention;

Embodiment

The present invention is further illustrated below in conjunction with drawings and Examples.

See also shown in Figure 1, the drawing tools that carries in the annex with computing machine is an example, at first open a picture interface 1, with a simple figure such as closed circular is example, if need the closed circular of a boundary line overstriking of picture, can utilize any one finger 2 to choose thickness icon 11 in the drawing tools earlier, on this picture interface, just can directly draw a closed circular 10 of specifying thickness then, so just finished the action of whole picture closed circular, as need be with the further overstriking in the boundary line of its closed circular, with regard to traditional method, a kind of is to operate again, promptly reselects the thickness icon, draw closed circular again, another then is to utilize finger picture closed circular earlier, and then selects the thickness icon, up to reaching customer satisfaction system effect.Above-mentioned two kinds of ways, which kind of mode all needs to point the repeated multiple times debugging when operation, operate more loaded down with trivial details, a kind of new method is provided now, please in conjunction with consulting shown in Fig. 2 A-2C, at first utilize any one finger as finger 2 to choose this closed circular 10, shown in Fig. 2 A, enter editing mode, can select the project such as the lines of required definite editing graph then by the mode that menu is selected, perhaps realize in order to need to determine the lines of this figure of editor as clicking lines by a specific gesture, utilize a finger 2 to exert pressure for this closed circular 10 then, continuous increase along with finger 2 pressure, the boundary line of this closed circular 10 is overstriking gradually also, shown in Fig. 2 B, this moment is if finger 2 stops to exert pressure, then the boundary line also can stop overstriking thereupon, this moment is if finger 2 leaves this picture interface 1, then this closed circular 10 just is located in the overstriking state after exerting pressure, if need with the state of Fig. 2 B again become the thinner state in boundary line, then can put at least two fingers, be put on this closed circular 10 as a finger 2, another root finger 3 is constantly exerted pressure on this picture interface 1, then the boundary line of this closed circular will be tapered, this moment is if finger 3 stops to exert pressure, then the boundary line also can stop to attenuate thereupon, and this moment, any one or two fingers in two fingers left this interface 1 simultaneously, and then this closed circular 10 just is positioned and remains on the state of finger when just leaving, shown in Fig. 2 C, so just realized editor to a figure thickness.

In like manner, if when in a closed circular, needing fill color color, at first need to select this closed circular, enter editing mode, then at project such as the color of selecting required editing graph by menu mode, perhaps realize in order to need to determine the color of editing graph as any place of clicking in this closed circular by a specific gesture, on to this closed circular, utilize a finger constantly to exert pressure then, increase along with pressure, color in its closed circular also can constantly be deepened and constantly be changed, and its aberration, parameters such as saturation degree all can constantly change along with the continuous increase of pressure, so do not need to repeat to select various figure table buttons to control the change of color, and directly can control the variation of color by the pressure of finger; And finger is if stop to exert pressure, then graphic color also can stop to change, this moment is if finger leaves this interface, then the color relation in this closed circular is located in the color state of finger when just leaving, if need the color after deepening is shoaled, then also need to put at least two fingers, a finger is put on this closed circular, another root finger is constantly exerted pressure on touch-screen, then the color of this closed circular can constantly shoal again, this moment is if finger stops to exert pressure, then the color of closed circular also can stop to change, and if any one or two fingers leave this interface simultaneously in two fingers, then closed circular just is positioned and remains on the shoal state of finger when just leaving, and has so just realized the editor to the figure color.

More than lines and the color with figure is example, and the method for pressure editing graph has been described, wherein related gesture is not only above-mentioned set gesture, and the user also can freely set according to the hobby of oneself.

Below also be example at an enterprising edlin of graphical interfaces that generates by user oneself fully, the user can certainly to one figure with regard to edlin, its principle and method are all similar, are not just repeating argumentation here.

Realize in the drawing tools that the present invention not only can carry in computing machine, and, also can realize same effect for the software of other similar support figure.
